NAME

       ppmtv - make a portable pixmap look like taken from an American TV

SYNOPSIS

       ppmtv dimfactor [ppmfile]

DESCRIPTION

       Reads  a  portable  pixmap as input. Dims every other row of image data down by the specified dim factor.
       This factor may be in the range of 0.0 (the alternate lines are totally black) to 1.0 (original image).

       This creates an effect similar to what I've  once  seen  in  the  video  clip  'You  could  be  mine'  by
       Guns'n'Roses.  In  the  scene I'm talking about you can see John Connor on his motorbike, looking up from
       the water trench (?)  he's standing in.  While  the  camera  pulls  back,  the  image  gets  'normal'  by
       brightening  up the alternate rows of it. I thought this would be an interesting effect to try in MPEG. I
       did not yet check this out, however.  Try for yourself.
